Clean room floors are industrial floors with special requirements for clean rooms in drug manufacturing, chip manufacturing and in hospitals. The most important properties are seamless , crack-free and low abrasion , so that the floors can be cleaned and disinfected easily. The pharmaceutical industry regulates all requirements for clean room floors in the VDI standard 2083.


Reaction resin top covering

The top coat are mostly reactive resin - screeds . These synthetic resin-bound coverings consist of free reaction resins, fillers, pigments as well as mineral and synthetic additives. The layer thickness is at least 5 mm, usually 8 to 10 mm.


  • High mechanical strength
  • Consolidated ground surface
  • Seamless
  • Flame retardant
  • Good resistance to chemical attack
  • No dust formation through abrasion
  • Sealed underground
  • Increased electrical conductivity
  • Conductivity in special constructions
  • Easy cleaning and disinfection

Floor covering made of tiles

Tile coverings in clean rooms are made of acid-resistant ceramic stoneware tiles. Porcelain-like ceramic plates can also be used; their surfaces are smooth and dense. The jointing compound, which can be made of phenolic resin, epoxy resin or polyester resin, is decisive for chemical and thermal resistance.

PVC covering

Plastic floor coverings made of polyvinyl chloride (PVC) are laid as sheet goods or panels with a thickness of 1.5 to 2 mm. These are bonded to the substrate using a dispersion adhesive. The joints are heat-welded using plastic welding cord.
